Application filed August 25, 1915. Serial No. 47,277.

To all whom it may concern:

Be it known that I, F INDLEY R. PAINE, a citizen of the United States, residing at the city of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Nozzles, of which the following is a specification.

My invention relates to nozzles, and the object of my invention is to provide a nozzle particularly adapted for distributing oil or other preparations for laying the dust and renewing the surface of highways; together with such elements and combinations as are hereinafter more particularly set forth.

I accomplish these objects by means of the mechanism illustrated in the accompanying drawings.

Figure l is a plan. Fig. 2 is an end elevation. Fig. 3 is a side elevation. vFig. is an elevation of the end opposite that shown on Fig. 2. Fig. 5 is an end view of barrel D. Fig. (3 is a section along the lines AA shown on Fig. 5. Fig. 7 is a section along the lines Bl5 shown on Fig. 5. Fig. 8 is a view of the end of the barrel'D which is opposite that shown in Fig. 5.

Similar letters refer to similar parts throughout the several views.

It is desirable when a fluid is to be applied to a road either for the purpose of laying the dust or to mix with a material adapted to re-surface the highway, that the spray or stream should be directed in a thin sheet of fan-like formation so that it will spread immecliately upon leaving the nozzle. It is also desirable, especially in the use of nozzles applied to cartsfor the delivery of oil or other fluid to a street or highway, that there need to be little or no regulation of the parts after they have onceybeen set for the particular use to which they are to be put, because these carts are generally under the guidance and control of those who have little or no judgment in reference to the proper amount of liquid that should be delivered from the orifice of the nozzle. It is desirable in the use to which this nozzle is especially applicable, that the flow of the liquid through it should be uniform and not affected in its uniformity of action by jolting or other violent, irregular and sudden motion. I have designed a simple, inexpensive, and extremely practical nozzle which may be regulated to permit of a larger or smaller stream from the nozzle as desired and which is provided with a means for locking the parts of the nozzle in such a position that the stream delivered therefrom will be uniform.

A casting E is open from end toend and about midway between its ends, F-G, 1 place a nipple H preferably provided with interior threads a adapted to screw onto a pipe (not shown), leading to the reservoir of fluid. By means of a webb J secured to or integral with the casting E and the nipple Ll, I pivot the fork 1i adapted to hang by gravity from the end of the casting as shown in Fig. 3 and Fig. l, but which may be raised to the position shown by dotted lines in Fig. 3. The casting E is provided in its side opposite the nipple l-Lwith a discharge opening L.

Into the casting hi I place a barrel D provided at one end with a square projecting hub 06, at the other end with a threaded post e and the squared shoulder f as shown in Figs. 6 and 7. The barrel 1) has a pair of passageways MM passing diametrically through it from side to side and separated from each other by a short distance, also a pair of passageways N-N extending diametrically through it at right angles to and intersecting the passageways M-M. The squared hub "(P is arranged so that the faces forming the sides of the squared portions, which are preferably numbered 1, 2, 3, and 4: are so adjusted that the openings of the passageways M-M and NN in each face of the barrel, are in a plane parallel to the face of the corresponding side of the squared hub. Between the openings of the passageways MM and N-N and each side of the barrel are placed discharge openings 0 and P respectively; the discharge openings between the passageways MM are connected by'oblique passageways RR with the passageways lN- M, in a similar way discharge openings P are connected by oblique passageways c3S with the passageways N N; the oblique passageways R and S differ in size so that when the openings P register with the discharge opening L of the casting, a larger amount of fluid will pass through that discharge opening L than when one of the other openings 0 is in register with the discharge opening L.

There can be, and preferably are, four sizes depending upon which of the four sections of the barrel D is in register With the discharge opening L of the casting and, therefore, there are four adjustments that may be made regarding thesize of the stream delivered by the nozzle. the purpose of readily adjusting the nozzle to deliver the proper stream that I have placed on the faces of the hub the numbers 1, 2, 3, and 4 which will show to the operator which size of delivery passage Ways are in register with the delivery orifice in the casting.

The fork K when in operative position rests with one of its tines on one side and one of'its tines on the other side ofthe squaredhub as shown in Fig. l, which will prevent the barrel from rotating. But when it is desired to change the position of the barrel, in order to cause a larger or smallerdelivery, the fork may be-raised, and, by means of a suitable wrench the barrel may-be rotated in either direction.

The size of the discharge orifice, .L,.and the distance between the openings of the passageways, M, M, and N, N, is such that only the discharge openings, P and O, register-with the discharge opening, L; passageways, M, M, and N, N, being covered by the side of the casting adjacent to the discharge opening, L, therein. It is to be noticed, however, that the nipple, H, is large enough to permit not only the openings, 1 andO, but also the openings to the passageways, M and N, to register therewith. By this arrangement the oil or fluid to be discharged enters through the nipple, H, and passes into all of the passageways, but discharges therefrom through two of the passageways only, namely, those two oblique passageways which register with the discharge opening, L, in the casting when the barrel is in the desired position. The arrangement of the passageways leading to the discharge orifice in a direction oblique to the vertical axis of the castin 'causes the stream discharged to be of fan-like formation, very similar to the flame of a gas burner. This provides for a thin sheet, Widely distributed and well adapted for the particular work for which this nozzle is es- It is for peciallyv designed. It is, of course, possible to rotate the barrel to apositlion where the flow is entirely shut as, by causing the discharge orifice, L,*to register between the orifices, O and P, of the barrel.

2. Ina nozzle, the combination of a hollow casting adapted to be secured to a source of liquid supply with a barrel adapted to be inserted into said casting, said barrel provided withtwo pairs of passagcwaysextending diametrically through the barrel from side to side, the passageways of one pair intercepting the passagewavs of the other pair inthe line of the aXisof the bar rel; four pairs of oblique passageways extending from each passageway of each pair to the surface of the barrel about midway between the openings of the passageways of said pairs respectively, said casting having a discharge opening adapted to register with the o enings of said oblique passageways; indicating means on the exterior of the barrel for showing which of the oblique passageway openings is inregister with the discharge opening in the casting; with means for locking the barrel in position in the casting.

In testimony whereof I have afiixed signature in presence of two witnesses.
